  Hereinafter, an operation lever device according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings. In the present embodiment, an example in which the operation lever device is provided near the steering shaft of an automobile and is configured to perform switching of a turn signal signal or a passing signal is taken as an example. FIG. 1 is a perspective view showing a configuration of an operation lever device according to the present embodiment, and FIG. 2 is an exploded perspective view thereof. 3 is a cross-sectional view of the operation lever device shown in FIG. 1 cut along line AA, and FIG. 4 is a cross-sectional view of the operation lever device shown in FIG. 1 cut along line BB.

  An operation lever device 1 shown in FIG. 1 includes a case 2 and an operation lever 3 supported in the case 2 so as to be swingable. As shown in FIGS. 1 and 2, a lever support 4 is provided at the base end of the operation lever 3, and a rotating spherical surface 4 a is formed on the lever support 4. In the case 2, at least a part of the rotating spherical surface portion 4a is spherically supported so that the center of curvature O does not move.

  In the present embodiment, the single lever support 4 is slidably supported on the spherical surface so that the operation lever 3 is crossed with each other in both the first direction (α direction) and the second direction (β direction). It can be configured to swing. In this embodiment, the case where the first direction (α direction) and the second direction (β direction) intersect (orthogonal) at 90 degrees is taken as an example, but the first direction (α direction) and the second direction (β direction) The crossing angle in the direction 2 (β direction) is not limited to 90 degrees.

  As shown in FIG. 2, the lever support 4 has a connecting shaft portion 4b protruding in one direction (base end side) from the rotating spherical surface portion 4a and a direction opposite to the connecting shaft portion 4b from the rotating spherical surface portion 4a. A distal end shaft portion 4c that protrudes toward the distal end side is provided. The operating lever 3 is connected to the connecting shaft portion 4b. The connecting shaft portion 4b, the tip shaft portion 4c, and the operation lever 3 are provided coaxially with the operation reference line L1 passing through the center of curvature O of the rotating spherical surface portion 4a. The rotating spherical surface portion 4a, the connecting shaft portion 4b, and the tip shaft portion 4c may be configured integrally or may be configured separately and connected by a fastening member such as a screw or a bolt. Further, the lever support 4 may be formed integrally with the base end portion of the operation lever 3.

  As shown in FIGS. 3 and 4, the case 2 is provided with a sliding support 2 a that slidably supports a part of the rotating spherical surface portion 4 a of the lever support 4. In FIGS. 1 and 2, the illustration of the sliding support 2a is omitted. The connecting shaft portion 4 b projects from the opening 2 b formed in the sliding support 2 a to the outside of the case 2 and is connected to the operation lever 3. The sliding support 2a is formed with a concave spherical sliding support surface 2c facing away from the opening 2b. The sliding support surface 2c has substantially the same curvature as that of the rotating spherical surface portion 4a. By causing the rotating spherical surface portion 4a to slidably contact the sliding support surface 2c, the lever support 4 is supported in a swingable manner in the state where the center of curvature O does not move. .

  In this embodiment, the lever support 4 is formed with a rotating spherical surface portion 4 a and the sliding support surface 2 c is also a concave spherical surface. However, the spherical surface portion or the concave spherical surface is formed between the lever support 4 and the case 2. The lever support 4 can be swingably supported in the case 2 by forming only one of them and forming a sliding part that slides on the spherical surface or the concave spherical surface on the other side.

  As shown in FIGS. 2 and 4, the turning spherical surface portion 4a is provided with a pair of protrusions 4g. The protruding portion 4g may be formed integrally with the rotating spherical surface portion 4a, or may be formed separately from the rotating spherical surface portion 4a and fixed to the rotating spherical surface portion 4a. The protrusion 4g is formed on a line that is orthogonal to the operation reference line L1 and passes through the center of curvature O.

  As shown in FIG. 4, a guide groove 2e is formed in the sliding support 2a of the case 2, and a pair of protrusions 4g are arranged inside the guide groove 2e. The guide groove 2e is a long hole extending in the left-right direction in FIG. 4, and the opening width in the direction orthogonal to the paper surface in FIG. 4 is formed to be approximately the same as the diameter of the protrusion 4g. Since the protrusion 4g is guided by the guide groove 2e, the lever support 4 can move in the β direction. However, since the protrusion 4g is restricted from moving in the direction perpendicular to the paper surface of FIG. It is restricted so as not to move in the rotation direction around the operation reference line L1.

  With this restriction mechanism, the operation lever 3 and the lever support 4 can be operated to swing in two directions, the α direction and the β direction.

  As shown in FIGS. 3 and 4, a swing guide mechanism 10 is provided inside the case 2. The operation guide 3 is guided in the first direction (α direction) and the second direction (β direction) by the swing guide mechanism 10, and the α direction and the β direction of the operation lever 3 are guided by the swing guide mechanism 10. The operating range is defined.

  The swing guide mechanism 10 has a cam surface 11, and a plurality of recesses that define the swing position (operation range) of the operation lever 3 are formed on the cam surface 11. As shown in FIGS. 3 and 4, the distal end shaft portion 4 c of the lever support 4 contains a sliding pin 4 d and a spring member 4 e that presses the sliding pin 4 d against the cam surface 11. The rotating spherical surface portion 4a is always pressed against the sliding support surface 2c by the reaction force with which the sliding pin 4d is pressed against the cam surface 11. Therefore, the rotating spherical surface portion 4a can swing with the position of the center of curvature O always fixed without leaving the sliding support surface 2c.

  The recess of the cam surface 11 guides the operation lever 3 to the operation position. In this embodiment, as shown in FIG. 8A, the cam surface 11 has recesses corresponding to nine operation positions. Has been. As shown in FIG. 8A, the concave portion a0 contacts the sliding pin 4d when the operation lever 3 is in the neutral posture. When the operating lever 3 is swung in the α direction from the recess a0 that is in the neutral position, the sliding pin 4d moves from the recess a0 to the operation position of the recess b0 or the recess c0. When the operating lever 3 is swung in the β direction from the recess a0 that is in the neutral position, the sliding pin 4d moves from the recess a0 to the operation position of the recess a1 or the recess a2. When the slide lever 4d is moved from the recess a0 to the recess b0 and the operation lever 3 is further swung in the β direction from the position, the slide pin 4d is moved from the recess b0 to the recess b1 or the recess b2. Move to.

  By using the cam surface 11 shown in FIG. 8, the operation lever 3 is swing-operated to a total of nine positions, three positions each in the first direction (α direction) and the second direction (β direction). be able to.

  Further, when the cam surface 11 is configured by smoothly connecting a plurality of concave portions, it is easy to return to the neutral posture after the operation lever 3 is swung. For example, if the concave portion b0 or the concave portion c0 is formed shallower than the concave portion a0 in which the operation lever 3 assumes the neutral posture, the operation force is removed after the operation lever 3 is swung in the α direction from the neutral posture. In addition, the operating lever 3 can automatically return to the neutral posture by the elastic force of the spring member 4e.

  Further, if the recess when moved in the β direction or the like is formed deeper than the recess a0 in the neutral posture, the operation lever 3 can be temporarily fixed at the operation position in the β direction. For example, if the hand is released when the operating lever 3 is swung in the β direction from the neutral position (recessed part a0), the operating lever 3 can be temporarily fixed at the position of the recessed part a1 or the recessed part a2. At this time, the operating lever 3 can be returned to the neutral posture by applying an external force to the lever support 4 toward the neutral posture by the holding release member.

  As shown in FIGS. 2 and 3, a second driving body 5 is provided inside the case 2. The second driver 5 is formed of a metal plate, and is formed by bending an engagement plate portion 5f, an upper support plate portion 5a, and a lower support plate portion 5b into a U shape. A support shaft 5c is fixed to the upper support plate portion 5a, and a support shaft 5d is fixed to the lower support plate portion 5b. As shown in FIG. 3, the lower support shaft 5 d is rotatably supported by the base 2 d in the case 2. Although not shown in FIG. 3, the upper support shaft 5 c is also rotatably supported inside the case 2.

  2 and 3 show the transmission reference line L3. The transmission reference line L3 is a virtual line fixed to the case 2. The shaft centers of the support shafts 5c and 5d coincide with the transmission reference line L3, and the second driving body 5 is rotatable in the β direction about the transmission reference line L3.

  As shown in FIG. 3, the rotating spherical surface portion 4a rotatably supported by the sliding support surface 2c is formed between an upper support plate portion 5a and a lower support plate portion 5b of the second driving body 5. The center of curvature O of the rotating spherical surface portion 4a is located on the transmission reference line L3.

  A guide hole 5 e is formed in the engagement plate portion 5 f of the second driver 5. The guide hole 5e is a long hole extending in a direction parallel to the transmission reference line L3. The distal end shaft portion 4c of the lever support 4 is inserted into the guide hole 5e. When the lever support 4 swings in the first direction (α direction), the distal end shaft portion 4c moves in the guide hole 5e, so the second driver 5 does not rotate. When the lever support 4 slides in the second direction (β direction), the distal end shaft portion 4c and the engagement plate portion 5f are engaged with each other, and therefore the second drive body 5 is also β together with the lever support 4. Swing in the direction.

  As shown in FIG. 2, a planetary gear mechanism 6 is used as a detection mechanism that detects the swing angle of the operation lever 3. By using this planetary gear mechanism 6, the rotating body 6a can be rotated at different angles when the operation lever 3 is swung in the α direction and when it is swung in the β direction. By detecting the rotation angle of the rotating body 6a with the magnetic sensor 7a, each swinging operation of the operation lever 3 can be determined and detected by one detection means.

  As shown in FIGS. 2 and 3, the rotating body 6a and the planet carrier 6e constituting the planetary gear mechanism 6 are supported so as to be able to rotate independently of each other about the transmission reference line L3.

  The support shafts 5c and 5d fixed to the second drive body 5 are rotatably supported on the transmission reference line L3 which is a fixed shaft, but the sun gear 6c is fixed to the upper support shaft 5c. . A shaft body 6h is integrally formed at the lower portion of the sun gear 6c. A support hole 6i is opened in the planet carrier 6e. As shown in FIG. 3, the shaft body 6h is inserted into the support hole 6i, and the planet carrier 6e is supported so as to be rotatable about the transmission reference line L3. The planetary carrier 6e is provided with a projection 6f, a plurality of planetary gears 6d are rotatably supported by the projection 6f, and each planetary gear 6d meshes with the sun gear 6c. Although FIG. 2 shows an example in which two planetary gears 6d are provided, the number of planetary gears 6d is not limited to that shown in FIG.

  The rotating body 6a has an internal gear that meshes with the planetary gear 6d. The rotating body 6a is rotatably held by a guide portion provided in the case 2 so that the rotating body 6a can rotate around the transmission reference line L3 while meshing with the planetary gear 6d.

  As shown in FIG. 2, a magnet 6b is fixed to the rotating body 6a. A substrate 7 that faces the rotating body 6 a is provided inside the case 2, and a magnetic sensor 7 a is provided on the substrate 7. The magnetic sensor 7a includes a magnetoresistive effect element such as a GMR element, a TMR element, and an AMR element. A plurality of magnetoresistive effect elements are provided to form a bridge circuit, and detection according to the rotation angle of the magnet 6b. Output can be obtained.

  The planetary carrier 6e is provided with a protrusion 6g protruding from the outer peripheral surface thereof. A first driver 8 is fixed to a protrusion 4g protruding from the rotating spherical surface 4a of the lever support 4. An engagement hole 8a that engages with the protrusion 4g of the rotating spherical surface portion 4a is formed at the base end portion of the first driving body 8, and the engagement hole 8a is fixed to the protrusion 4g so as not to rotate. . A guide groove 8b into which the projection 6g of the planetary carrier 6e is slidably inserted is provided at the tip of the first driver 8. As shown in FIGS. 2 and 5, the axial center of the protrusion 4 g is a support center line L <b> 2 that serves as a rotation fulcrum of the first driver 8.

  As shown in FIG. 5, when the rotating spherical surface portion 4a rotates in the first direction (α direction), the tip of the first driver 8 swings around the support center line L2, and the protrusion 6g slides. Then, the planet carrier 6e is rotated. Thereby, the planet carrier 6e rotates according to the swinging motion of the operation lever 3 in the first direction (α direction).

  Next, the swinging operation of such an operating lever device will be described in more detail with reference to the drawings. FIG. 5 is a perspective view for explaining the operation of the operation lever device according to the present embodiment. FIGS. 6A to 6C are operation explanatory diagrams when the operation lever in the present embodiment is swung in the first direction (α direction). FIGS. 7A to 7C are operation explanatory views when the operation lever according to the present embodiment is swung in the second direction (β direction).

  As shown in FIG. 5, when the operating lever 3 swings in the first direction (α direction), as shown in FIGS. 6A to 6C, in conjunction with the rotation of the lever support 4, 1 The driver 8 tilts to rotate the planet carrier 6e. At this time, since the second driving body 5 does not rotate, the sun gear 6c does not rotate.

  For example, when the operating lever 3 is swung in the α1 direction (first direction) from the neutral posture shown in FIG. 6B, the sliding pin 4d moves from the concave portion a0 in the neutral posture and engages with the concave portion b0. . At this time, as shown in FIG. 6A, the first driver 8 is inclined in the direction of the arrow in the figure. Thereby, the planetary carrier 6e rotates with respect to the sun gear 6c by the angle at which the first driver 8 is inclined without rotating the sun gear 6c.

  When the operation lever 3 is swung in the α2 direction (first direction) from the neutral posture shown in FIG. 6B, the sliding pin 4d moves from the concave portion a0 in the neutral posture and engages with the concave portion c0. At this time, as shown in FIG. 6C, the first driver 8 is inclined in the direction of the arrow in the figure. Thereby, the planetary carrier 6e rotates in the direction opposite to that shown in FIG. 6A by the angle at which the first driving body 8 is inclined without rotating the sun gear 6c.

  When the operation lever 3 swings in the first direction (α direction), the planetary gear 6d rotates while revolving around the sun gear 6c without rotating the sun gear 6c, and the planetary gear 6d The rotating body 6a is rotated in the same direction as the planetary carrier 6e via the meshing internal gears.

  The rotation angle of the rotating body 6a at this time is determined by the number of teeth Z1 of the sun gear 6c and the number of teeth Z3 of the internal gear formed on the rotating body 6a. The rotation angle of the rotating body (as well as the internal gear) 6a is amplified by (Z1 + Z3) / Z3 times the rotation angle of the planet carrier 6e. For example, if Z1 = 16 and Z3 = 48, the speed is increased to (Z1 + Z3) /Z3=1.33 times.

  On the other hand, when the operation lever 3 swings in the second direction (β direction), as shown in FIGS. 7A to 7C in conjunction with the rotation of the lever support 4. Since the second driving body 5 rotates, the sun gear 6 c also rotates at the same angle as the second driving body 5. At this time, the first driving body 8 rotates together with the lever support body 4 without tilting, so that the planet carrier 6e rotates by the same angle as the rotation angle of the second driving body 5 (rotation angle of the sun gear 6c). For this reason, the planet carrier 6e does not rotate relative to the sun gear 6c.

  For example, when the operating lever 3 is swung in the β1 direction (second direction) from the neutral position shown in FIG. 7B, the sliding pin 4d moves from the concave portion a0 in the neutral posture and fits into the concave portion a1. To do. At this time, as shown in FIG. 7A, since the sun gear 6c and the planet carrier 6e rotate by the same angle in the same direction, the planet carrier 6e does not rotate relative to the sun gear 6c. The rotation angle of the rotating body 6a at this time is the same as the rotation angle of the lever support body 4 in the β1 direction.

  When the operating lever 3 is swung in the β2 direction (second direction) from the neutral posture shown in FIG. 7B, the sliding pin 4d moves from the concave portion a0 in the neutral posture and fits into the concave portion a2. At this time, as shown in FIG. 7 (c), the sun gear 6c and the planet carrier 6e rotate in the same direction by the same angle and in the opposite direction to FIG. 7 (a). On the other hand, the planet carrier 6e does not rotate relative to each other, and the rotation angle of the rotation body 6a is the same as the rotation angle of the lever support body 4.

  Thus, when the operation lever 3 swings in the second direction (β direction), the planetary carrier 6e does not rotate relative to the sun gear 6c, and the rotating body 6a is the lever support 4 Only rotate the same angle as.

  According to such a configuration, the rotating body 6a rotates when the lever support 4 is swung in the α direction (first direction) and when it is swung in the β direction (second direction). The angle can be made different. Therefore, when the operation lever 3 is moved to a plurality of operation positions, the rotation angle of the rotating body 6a when reaching each operation position can be set without overlapping each other.

  For example, as shown in FIG. 8A, when the operation position of the operation lever 3 is 3 positions each in the first direction (α direction) and the second direction (β direction), a total of 9 positions. The rotation angle at each position of the rotating body 6a is as shown in FIG. 8B, for example.

  For example, when the sliding pin 4d is swung in the first direction (α direction) from the neutral position where the sliding pin 4d is fitted in the recess a0, and the sliding pin 4d is fitted in the recess b0 or the recess c0, Due to the action of the planetary gear mechanism 6, the rotation angle of the rotating body 6a is increased. Assuming that the rotation angle of the rotating body 6a at this time is P, angles b0 and c0 that are separated from the neutral posture angle a0 in FIG. 8B by the rotation angle P in the opposite direction are fitted in the recesses b0 and c0, respectively. Corresponds to position.

  On the other hand, the sliding pin 4d is swung in the second direction (β direction) from the neutral position where the sliding pin 4d is fitted in the recess a0, and the sliding pin 4d is fitted in the recess a1 or the recess a2. In this case, the rotation angle of the rotating body 6a is smaller than the angle P when the rotating body 6a is swung in the first direction (α direction) by the action of the planetary gear mechanism 6. If the rotation angle of the rotating body 6a at this time is Q, angles a1 and a2 that are separated from the neutral posture angle a0 in FIG. 8B by the rotation angle Q in the opposite direction are fitted in the recesses a1 and a2, respectively. Corresponds to position.

  Further, when the sliding pin 4d is swung in the second direction (β direction) from the posture in which the sliding pin 4d is fitted in the concave portion b0 or the concave portion c0, the angles b0 and c0 shown in FIG. The angles b1 and b2 or the angles c1 and c2 that are separated from each other by the rotation angle Q correspond to the positions of the recesses b1 and b2 or the recesses c1 and c2, respectively.

  Thus, the rotation angle Q of the rotating body 6a by the swinging motion in the second direction (β direction) is more than the rotation angle P of the rotating body 6a by the swinging motion in the first direction (α direction). Get smaller. Moreover, the difference between the rotation angles P and Q is determined according to the number of teeth of the gears 6a, 6c, and 6d and can be extremely large. For this reason, as shown in FIG. 8B, the rotation angles of the rotating bodies 6a corresponding to the swinging operations of the operation lever 3 do not overlap each other and correspond to the rotating angles of the rotating bodies 6a. be able to. Accordingly, it can be understood that all the swinging motions of the operation lever 3 can be detected by one detection member (sensor) that detects the rotation angle of the rotating body 6a.

  As described above, in the operating lever device according to the present embodiment, since all the swinging motions of the lever support 4 can be detected by one sensor, the number of parts can be reduced and the operational reliability can be improved. In addition, since the operation reference line L1 can be swung in both the first direction (α direction) and the second direction (β direction) with one lever support body 4, this also reduces the number of mechanical components. Thus, operational reliability can be improved.

  In the present embodiment, as described above, the magnetic sensor 7a is used as the detection member, and the rotation angle of the rotating body 6a is detected in a non-contact manner. The contact area can be reduced. For this reason, since it is possible to suppress the occurrence of rattling and wear during operation as in the prior art, the operational feeling can be improved. The detection member for detecting the rotation angle of the rotating body 6a is not limited to a magnetic sensor, and any detection member that can detect the rotation angle of the rotating body 6a, such as an encoder or an optical sensor, is used. It is also possible to use it.
